In software product development, there are a lot of good methods – in other words, well-known best practices. You have to think about how the project is going to be, how much money you have to work with, your own preferences, and even how you feel about the project manager.
To learn more about outsourcing software development, we’ll look at seven of the most common ways to build things. We’ll also talk about outsourcing software development pros and cons.
- One of the names for this model is “Waterfall Model” (cascade model or “waterfall”)
One of the oldest ways to do things is to go through a series of stages, each of which must be done completely before the next one can start. Easy: The Waterfall model makes it simple to run a project. Due to its rigidity, the project moves quickly, and the cost and time are already known. But this is a two-edged sword. The waterfall model is only good for projects that have clear requirements and a clear plan for how they will be done. There isn’t a way to go back, because testing only starts when the development is done or close to being done. Products made using this model without a good reason may have flaws (the list of requirements can’t be changed at any time), which only come to light at the end because of the strict order of actions. The cost of making changes is high because you have to wait for the whole project to be done before you can start it. Even so, the fixed cost often outweighs the drawbacks of this method. In our experience, adding one to three more agreements to the contract with a small technical specification is all that is needed to fix problems that were found during the process of making the thing you want.
- The “V-Model” is another name for this.
The waterfall model took the step-by-step structure from it. V-shaped models are good for systems that need to stay running at all times. For example, there are programs in clinics that help doctors keep an eye on patients, software that helps cars’ airbags work together, and so on. A feature of the model could be that it is used to make sure that a product that is still in the early stages of design is done right. The testing phase is done at the same time as the development phase. For example, unit tests are written while the code is being written.
- “Incremental Model” is the third (incremental model)
In an incremental model, the whole system is broken down into smaller parts called “assemblies.” There are a lot of different words that are used to describe a staged build of the software. There are a lot of different stages of development, and together they make up the multi-waterfall lifecycle. The cycle is broken down into smaller parts that can be made quickly. Each module goes through the steps of defining the needs, designing, coding, implementing, and testing. In the incremental model, the product is released at the first major stage in its basic functionality, and then new features, or “increments,” are added to it on a regular basis, making the product better and better. The process keeps going until a complete system is made.
- This is called the “RAD Model” (rapid application development model or rapid application development)
In this case, the incremental model is different from the RAD model. In the RAD model, a lot of very skilled people work on parts or functions at the same time, like a lot of small projects. The time frame for one cycle is very strict. The modules are then put together to make a working prototype. When you use Synergy, you can show the client something that is working quickly so that they can give you feedback and help you make changes.
- The “Agile Model” (agile development methodology)
In the “agile” development method, after each iteration, the customer can see the result and figure out if he likes it or not. When you have a flexible model, this is one of the things that you can do. It has some drawbacks, like the fact that there aren’t specific formulas for the results, which makes it hard to figure out how much time and money it will take to make. Extreme Programming (XP) is one of the most well-known ways to use the agile model in real life.
There are “Scrums” and “Sprints” in this type of meeting. They usually happen once a week, once every two weeks or once a month.
- “Iterative Model” is the name of this (iterative or iterative model)
The iterative life cycle model doesn’t start with a detailed description of what needs to be done. Instead, the creation process starts with the implementation of a piece of functionality, which serves as the foundation for figuring out what else is needed. Repeating this process is what makes it happen again and again. Because it works, even if it’s not perfect, the main thing is that it does. We try to reach our goal so that each step is effective, and each version can be used.
- The “Spiral Model” (spiral model)
It looks a lot like the incremental model, but with a lot more emphasis on risk analysis. It’s good for business problems where failure would be bad for the company’s operations, new product lines, research, and field tests.
